ADKAR Model: Individual Change Adoption Framework

Prosci (Jeff Hiatt) 2003 Medium Complexity

ADKAR is an individual-level change adoption model: Awareness, Desire, Knowledge, Ability, Reinforcement. It diagnoses where people are stuck and guides targeted interventions.

What Is It?

ADKAR, developed by Prosci's Jeff Hiatt in 2003, recognizes that organizational change happens one person at a time. While frameworks like Kotter's 8-Step address organizational transformation, ADKAR focuses on the individual journey.

The five elements are sequential: Awareness of why change is needed, Desire to participate and support, Knowledge of how to change, Ability to implement new skills and behaviors, and Reinforcement to sustain the change.

ADKAR works as both a change model and a diagnostic tool. Assess where individuals are stuck (first element scoring below 3) and apply targeted interventions. It complements organizational models and pairs well with Bridges' Transition Model for emotional aspects.
